Android Central notes that the method is "pretty easy, doesn't require root and is the official upgrade just as if you had been waiting for it to push to your device. " What's more, AndroidGuys adds that "this is only for non-rooted stock 2.1 users."

1. Download the official Android 2.2 firmware from: Android 2.2 (FRG01B)
2. Copy the file to your microSD card and name it update.zip (newb warning: not update.zip.zip)
3. Power off your phone. Hold down the “X” button on the physical keyboard and power it back on to boot into recovery mode.
4. When you see the “/!\” symbol, press volume up and the camera button to display the recovery options.
5. Use the d-pad to navigate to “apply sdcard:update.zip” and select it.
6. When you see “Install from sdcard complete”, select “reboot system now”.
7. Great success!

As for how it works, AndroidPIT member Randy Merrellnotes that there are "noticeable improvements" in the speed and that "the camera app is muich improved." There is some bittersweet news though, as tethering is there, "but Verizon wants you to sign up for it."

AndroidandMe writes that this version of FroYo makes it a bit harder to get Flash 10.1, because "it is not appearing in the Market yet for updated Droid users, but according to Jeice it will allow you to get it directly from this page on Adobe’s site."
